Conventional management of Parkinson's disease (PD) is limited. The pharmaceutical and surgical options that are available have significant side effects and only correct symptoms for a limited period of time. Even with the best conventional treatment, the disease progresses and becomes severely disabling. No existing conventional therapies that the progress of the disease; available medicines only treat symptoms temporarily. Conventional medicine views the course of the disease as "progressive" and "irreversible." Many patients, who are only partially satisfied with conventional medicine, seek alternative and complementary options in an attempt to slow, stop, or reverse the disease process.
